How to guarantee the service life of lithium-ion large-capacity lithium-ion batteries?

Haha, after some nonsense, I always have to remind that many people who get an electric car will leave the manual aside and choose to ignore the boring words. The general sequelae are that the motor burns out and the large capacity lithium ion is charged. If there is a problem with the battery, choose to call the customer service. If the customer service fails to solve it, a lot of time and money will be wasted. And the general manual will have a complete guide, as well as the correct trial methods and after-sales maintenance methods for large-capacity lithium-ion batteries. In fact, as long as the manual is read in detail at the beginning, the problem can be solved. 2. When using lithium-ion large-capacity lithium-ion batteries for charging frequency, we should try our best to prevent the battery from being completely used up. Deep use of power can easily degrade the performance of large-capacity lithium-ion batteries. Therefore, in daily life, when using electric vehicles, Try to put the habit of diligence as shallowly as possible. For example, a general power-assisted bicycle, when 20% of the large-capacity lithium-ion battery is left, the low-power protection function is activated to protect the large-capacity lithium-ion battery. The general power-assisted function cannot be used, and only the pedals can be used. , And at this time, the car’s large-capacity lithium-ion battery will be charged, and all functions will be restored after charging. 3. Charging time. At present, most office workers use electric vehicles during the day to work, and at night they generally charge the lithium-ion large-capacity lithium-ion batteries of electric vehicles. Generally, they can be fully charged in one night, but if they have fallen asleep, or in the morning Forgetting to unplug the power source, it will cause the large-capacity lithium-ion battery to be overcharged and excessive internal circulation. This situation is no less harmful than the deep discharge, which in turn affects the service life of the charged large-capacity lithium-ion battery. Generally, when charging for the first time, follow the principle of 12 hours of charging, and for subsequent use, it is sufficient to charge the lithium-ion large-capacity lithium-ion battery for 8 hours. After the customer has used it for a long time, there will naturally be a general charging rule, either every few days, or the proportion of the remaining power (usually 20%-50%), and even some users will choose how many miles they run to charge. One time electricity is reasonable. 4. Temperature large-capacity lithium-ion batteries must have a suitable environment for use, which emphasizes the use temperature, storage environment temperature, and charging temperature, basically in accordance with the normal standard range, which is about 20°C-40°C. Sometimes, the temperature of the use environment is too low or high. Too high or too low temperature will affect the service life of large-capacity lithium-ion batteries. If it is too high, you may think, why is it too low? Because in a cold environment, the battery is generally not fully charged, which is 70% to 80%. In order to prevent accidental risks, generally stay away from fire when charging. At the same time, when you try to buy lithium-ion large-capacity lithium-ion batteries, use the original lithium-ion large-capacity lithium-ion batteries, which will prevent the large-capacity lithium-ion batteries from heating up. , Smoking or even explosion. 5. Long-term idle Li-ion large-capacity lithium-ion batteries that have been idle for a long time should at least be stored with full power. Try not to keep empty for a long time. This will shorten the life of large-capacity lithium-ion batteries and may not be able to charge them again. In fact, storage of less than 20% or more than 90% will damage the high-capacity lithium-ion battery. The correct method is to keep the large-capacity lithium-ion battery at 50% when it is ready to be idle, and charge and discharge it on time in three weeks or a month.
